Prometheus ePAS vs Zentri comes down to one thing. Prometheus ePAS, a configurable permit and isolation system with close SAP ties, standardises permit workflows well across many sites. Zentri's Permit to Work module records each permit as it happens, to your SOP. You get the whole crew in view, every override explained, and audit evidence complete at close. Zentri is stronger on the live permit record.
- Choose Prometheus ePAS if you run SAP across many sites and want permits, isolations and maintenance planning from one vendor.
- Choose Zentri if you want permits built to your process, a crew you can see on every job, and evidence ready before anyone asks. Permit to Work is sold on its own.

What is Prometheus ePAS?
Prometheus ePAS (Electronic Permit Administration System) is a permit and isolation system from Prometheus Group of Raleigh, North Carolina. It also covers risk assessments, management of change and incidents. Its strength is the link to maintenance: it integrates with SAP, Oracle or IBM Maximo, so a permit request can come straight from a work order.
Where they differ
The crew on the permit
ePAS checks every worker at sign-on. Zentri tracks the whole crew to close-out, standby included. ePAS sets approvals per site and can check each crew member's ID and qualifications (Prometheus). Zentri's permit carries your own sections, risk assessment, gas test and PPE check, with approvers at start and close-out. Crews sign on and off by phone, and the permit names who is standing by. The issuer sees who is working, on watch or signed off, from the permit itself.
Permits and isolations, linked
Both hold a permit until its isolation is confirmed. Zentri records any override, with its reason. ePAS rules can hold a dependent permit until its lockout is issued and verified in the field (SAP). Add Zentri's Lockout Tagout, sold separately, and the permit is digitally linked to the lockout it depends on, showing each isolation live: in place, in progress or verification pending. Signing over an isolation that isn't ready is recorded with a written reason, so the record shows who decided and why.
Proof at audit time
ePAS time-stamps every permit step. Zentri's trail is never edited and exports to PDF. ePAS logs each permit action automatically, with names and times, and runs scored audits of your safety documents. Each Zentri permit keeps its own timeline, and the audit trail records every approval, sign-on, signature and override, with who and when. Nothing is deleted, and you filter by user, action or date. When the auditor arrives, the evidence is an export, not a week pulling permits.
When Prometheus ePAS is the better fit
- Your maintenance already runs on SAP and Prometheus planning tools, and you want permits raised from the same work orders.
- You are standardising permits, isolations and management of change across many large sites under one set of rules.
When Zentri is the better fit
- You want one comprehensive permit-to-work solution that actively tracks the work as it happens, from the first sign-on to close-out.
- Contractor crews come and go under your permits, and you need to see who is on the job.
- You want evidence that holds up on the bad day: an OSHA inspection or an incident investigation.
- You have your own procedures and want the software configured to them, not the reverse.

Switching from Prometheus ePAS to Zentri
Your permit types are rebuilt as Zentri permit templates, from modules, in your own phases and with your own approvers. If you add Lockout Tagout, your lockout procedures and equipment come through a guided import workbook. We configure Zentri to your SOP, build custom, bidirectional integrations with SAP and your other systems, and train your team. A pilot site typically goes live in 4 to 8 weeks.
